Did i have right understand? Change layer colors to ByLayer?Of course you can do it but this could crash AutoCAD or dwg file (can't open it next time). I receive this error one time and have no wishes to repeat it.Layer objects can't be with color ByLayer or ByBlock. You have to set color by ACI (from 1 to 255) or TrueColor.

So you want all of the objects to be color bylayer, right? Example: A line is drawn on layer "TEMP" and layer "TEMP"'s color is blue, but the line shows as red, you want that line's color property to be changed to BYLAYER instead of 1 (red), correct?

If you're using 2008, SETBYLAYER is by far the best/fastest way to accomplish this.

If not, we'll have to come up with something (unless somebody has already rolled one that they'd like to pass around).
